I dun go there for service. But a friend of mine went to unity
lately and spent $1k going up his brakes system. 3 pieces of discs
(braking) and EBC 'HH' grade pads. Including a whole set of 3 good
ridge. And apart from this, he also went there to do a top overhaul
on his engine and his SRAD carburettor. After the services, he
returned and told me that their service was superb. Every single
dollar spent was worth it. Unity is involved in races at pasir
gudang with their R6. And i've personally seen their track bikes
are of high standard servicing done to the last bolt and nut. But
I've not tried their services yet. So I can only tell you as a 2nd
hand experience.
But for EXCEL cycles, 'Big Boon' is good at doing bikes. I've tried
there. Until now no regrets too. Except that his boss is a very
good swordsman. So Often I was badly injured by his lightning sword
that my wallet tore many times.
